摘　　要：水凝胶作为软物质的成员之一,是一种具有三维网络结构的新型功能高分子材料,以其含水量高、溶胀快、生物相容性好、对外界刺激响应灵敏等性质而被广泛应用于不同领域。本项目从生活中常见的果冻零食、水精灵玩具出发,逐步深入到适宜3D打印的水凝胶、可变形的水凝胶、基于热刺激的记忆-遗忘型水凝胶,面向不同的受众群体分层次科普水凝胶的知识、体验不同类型水凝胶的制备及性质探究实验,深入浅出地阐释实验背后的化学原理,提升公众的化学素养。As a member of soft matter,hydrogel is a new type of functional polymer material with a three-dimensional network structure.Due to the properties of high water content,fast swelling,good biocompatibility,and sensitive responsiveness to external stimuli,hydrogels have been widely used in various different fields.Starting from the common jellies and water-elf toys in life,this project gradually goes deep into 3D-printing technology hydrogels,deformable hydrogel,and memorizing-forgetting hydrogel based on thermal stimulation.For different audiences,we have popularized the knowledge of hydrogels at different levels,experienced the preparation and properties of different types of the hydrogels,and explained the related chemical principles,so as to improve the public chemical literacy.
